Abstract
The utility model relates to a ball valve, which uses a thin wedge-shaped structure and is arranged on one side face by using a ball body. The left side of an inner cavity of a main valve body and the contact face of a valve base are processed into an inclined surface which forms an inclined angle about 5 DEG +/-30' with a shaft central line of the valve body. The side valve body and the contact surface of the valve base are processed into an inclined surface about 5 DEG +/-30'. After the wedge-shaped ball body is arranged, the wedge-shaped ball body drives two valve bases to slide along the inclined surface under the impulsion of a compression spring and the inner pressure of liquid. A left inclined surface and a right inclined surface of the thin wedge-shaped ball valve can be respectively processed to solve a manufacturing problem. The utility model has the advantages of short structure, light weight, convenient assembly and disassembly, and convenient repair, and the length of the valve body is compressed. The ball valve also has the advantages of reasonable structure, simple manufacturing technology, reliable function of clearance compensation, reliable sealing effect, can be combined with different materials, and is suitable for various poor operating conditions with high temperature, high pressure, and strong corrosion.
Description
The utility model relates to a kind of sealed valve.
As everyone knows, valve extensive use in industries such as oil, chemical industry, machinery, electronics, food, building.Particularly ball valve is compared with other valve class, and compact structure is in light weight, has less fluid impedance losses, thereby development is very rapid.But ball valve in use, because spheroid and sealing surface produce friction, valve leaked, and how to solve this difficult problem, becomes the problem that the vast scientific and technical personnel that are engaged in valve working research press for solution.We study successfully a kind of Wedge shape ball valve in practice, it adopts wedge principle, be processed into 5 ° of inclined-planes in the body cavity both sides and constitute the angle of wedge, Wedge shape ball valve is the all-pass footpath, under the promotion of in pressure spring and fluid, pressing, make wedge shape spheroid band left and right valve seat to lower slider, has the gap compensate function, favorable sealing property, but because this kind Wedge shape ball valve is to go up the dress formula, the wedge shape spheroid must force valve gap and size suitable for reading bigger than normal in the valve body chamber of packing into suitable for reading, valve body structure is oversize, brings very big difficulty to processing.
The purpose of this utility model is to provide a kind of slim Wedge shape ball valve, adopt side-mounted assembling, overcome last dress formula valve body middle part and must increase volume, the disadvantage that valve gap also increases has simultaneously enlarged latus rectum, compressed volume, have reliable gap compensate function, sealability is reliable, makes up with different materials, applicable to high temperature, high pressure, the various harsh operating modes of deep-etching, be a kind of desirable ball valve.
Technical solution of the present utility model is to utilize the chock principle design, in main valve body 1, be processed on the surface of contact of left surface and valve seat 3 be with the valve body shaft centre line tilt 5 ° ± 30 ' the inclined-plane, on side valve body 16 and valve seat 3 surface of contact, be processed into 5 ° ± 30 ' the inclined-plane, work as the master, after the assembling of side valve body, its left side, inclined-plane, right both sides constitutes wedge shape, wedge shape also is processed in the spheroid both sides, when a wedge shape spheroid and a left side, right valve seat is embraced together, after the angle of wedge of packing into simultaneously is interior, under the promotion of in pressure spring and fluid, pressing, make the wedge shape spheroid drive two valve seats along the inclined-plane to lower slider, downward more sealing effect is good more.
Formation of the present utility model comprises valve body, wedge shape spheroid 2, valve seat 3, outer shroud 4, valve rod 11 and is enclosed within the spring 5 of valve rod 11 bottoms, the sealing gasket 6 that is used for 11 of valve body and valve rods, filler 18, clamping sleeve 7, packing ring 10 and the spanner 14, the limiting board 13 that are assembled on the valve rod 11, valve body is made up of main valve body 1 and side valve body 16 two-part, by adjusting pad 18, be assembled between two ones with fastening hexagon socket head cap screw 17.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural drawing of thin Wedge shape ball valve.
Embodiment 1:
Inner chamber with the main valve body 1 of packing into simultaneously behind 2 armfuls of upper valve bases 3 of wedge shape spheroid, the outer shroud 4, load onto side valve body 6 subsequently and adjust pad 8, fastening hexagon socket head cap screw 17, at this moment spring 5 is enclosed within on the valve rod 11, valve rod 11 is shifted onto in the flat hole of spheroid 2, pack into and fill up 6, refill clamping sleeve 7, filler 8, pressure cap 9, pad 10, with nut 12 fastening clamping sleeves 7, limiting board 13 is contained on the clamping sleeve 7, spanner 14 is contained in valve rod 11, and fastening with nut 12 above, valve rod 11 bottoms and wedge shape spheroid 2 flat holes are cooperating structure.
When the assembling of thin Wedge shape ball valve, attention should be earlier with the big end of the wedge shape ball angle of wedge, after the side valve body compresses, utilize valve rod to compress, and under the thrust of spring, the wedge shape spheroid is driven the both sides valve seat push small end to, thereby finish whole fittages, carry out intensity and leakage test.
Above-mentioned thin Wedge shape ball valve adopts side-mounted structure, utilizes the chock principle, the top is big, following little, after master, the assembling of side valve body, its and arranged on left and right sides inclined-plane constitutes wedge shape, wedge shape also is processed in the spheroid both sides, embrace with left and right valve seat when the wedge shape spheroid and to be in the same place, in the angle of wedge of packing into simultaneously after, under the promotion of in pressure spring and fluid, pressing, make the wedge shape spheroid drive two valve seats along the inclined-plane to lower slider, downward more sealing effect is good more.
The utility model great advantage is to utilize wedge principle, makes thin Wedge shape ball valve, and it adopts The all-pass aperture utilizes side-mounted structure, makes the inclined-plane of wedge shape arranged on left and right sides be more convenient for processing, Owing to compressed valve body length, structure is short, and is in light weight, and the loading and unloading maintenance is more convenient, this ball valve knot Structure is reasonable, and manufacturing process is simple, saves cost, and significant economic benefit is arranged, and has reliably Clearance compensation function, sealing effectiveness is reliable, with the different materials combination, applicable to high temperature, height Pressure, the various harsh operating modes of deep-etching are a kind of desirable ball valves.
